Practical Dynamo - Apply Parameter Values (Using Saved Selection Sets)

For the next installment of the "Practical Dynamo" mini-series I am going to expand on the last script (which utilized Dynamo to apply parameter values to multiple objects).  The previous script worked but you have to manually select the elements and add them to your node in Dynamo.  This can be cumbersome and also cause you to select elements twice if you are trying to add something like a building area parameter.

My first solution was creating save selection sets... Then using those sets to isolate the elements, select the elements in Dynamo, run the script, un-isolate, and repeat... Yeah, I know...  It sounds ridiculous.  Well, my first rule of thumb in Revit (and now Dynamo) is if it seems like its taking too long there is probably a better way to do it... So I found a better way...

I have been posting little screenshots on Twitter of current Dynamo scripts and people seem to love them.  One of the cool things about Dynamo is you can see a simple snippet of all the nodes and recreate the script pretty effectively.  Its a method I have used when learning Dynamo.  It helps me to use different nodes, search for packages, and understand logic.  Well, I thought it would be a good mini-series here on the blog.  The first script I am going to show you is very simple but includes some nice booleans, logic, and nodes.
